Title: Display controller
Inventor: EITOUKEN ANDORIYUU PIITAA
IPC: G09G3/20
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To supply the memory access of an excellent level to the other user of a memory and to perform manufacture at a relatively low cost by executing heterogeneous or asynchronous data transfer from a memory means to a display means. SOLUTION: A memory interface block 16 executes an asynchronous transfer protocol for the memory access and executes the arbitration of memory access requests between a display driving device and one or plural other interfaces indicated inside the memory interface block 16. By using the heterogeneous or asynchronous data transfer in such a manner, many restrictions to a timing by a synchronous operation are eliminated and free and optimum memory access by a display device and the other memory user is made possible. Thus, influence on performance and the restrictions on the design of the display device or the other memory interface are minimized.

Abstract: PURPOSE:To prevent the injury of a sheet and double feeding in a device equipped with a forward roller and a reverse roller, by arranging a roller whose motion follows sheet feeding motion on the same shaft of the reverse roller and making it act as both an auxiliary roller and a guide plate. CONSTITUTION:A forward roller 1 for normal driving is fitted on a driving shaft 8a, and rubber rollers 2a, 2b constituting a reverse roller 2 are fitted on a shaft 8b arranged oppositely to the drving shaft 8a. Furthermore, a driven roller 9 is set freely on the shaft 8b so that it can make relative movement to the rubber rollers 2a, 2b as it is put between the rubber rollers 2a, 2b. At the time of feeding a sheet, when the lowest sheet 3 is fed separately, a just upper sheet 4a is held in an upstream position (l) from the common center of both rollers 1, 2 by the reverse roller 2. On the other hand, as the rotation of the driven roller 9 follows the rotation of the forward roller 1, the sheet 3 is held between the rollers 1, 9 and fed without turning up or double feeding.

Title: Numerically controlled machine tool
Inventor: KAWAMURA HIDEAKI
IPC: G05B19/4068
Filed: 1986-01-20
Abstract: PURPOSE:To start working operation immediately after a tape checking process is finished by making the coordinate values of a movable part in the storage part of a numerical controller coincident with the actual coordinate values of the movable part. CONSTITUTION:A machine lock signal turns on and then a control means 6 transfers the coordinate values of the movable part stored in the numerical controller 2 to a register 5 at the point of time to perform a tape checking process. The coordinate values in the device 2 vary successively and a servo device 3 is in an off state, so that the actual coordinate values of the movable part do not vary from their starting values. Then, the coordinate values of the movable part in the device 2 do not coincide with the actual movable part coordinate values at the end of the checking process. Consequently, the movable part coordinate values in the register 5 are read in the device 2 under the control of a control means 6 and corrected. Consequently, the stored values and actual values are coincident with each other and working operation is started.

Title: Code converter
Inventor: SHINKAWA HIROSHI
IPC: H03M7/50
Filed: 1987-01-19
Abstract: PURPOSE:To realize a code converter only with a conversion circuit relating to the expansion by generating addresses of a conversion list in the ascending order sequentially, reading an expanded signal level and stopping the generation of address when the level reaches a quantized input signal or over, and using the address at that time as a compressed signal level. CONSTITUTION:A received PCM signal is divided into a sign bit (1 bit) and signal bits (7 bits) subject to parallel processing and the signal bits representing an input signal level is fed to a terminal (a) of a selector (SEL) 82. The said count (7 bits) fed to a ROM 5 via a terminal (b) of the SEL 82 is treated as an input signal address of a conversion list (TB) 51 and an expanded signal level in 12-bit is fed to a terminal (c) of a comparator circuit (CP) 91. A CP 91 compares the expanded signal level supplied one after another together with the increase in the count with a uniformly quantized input signal in 12-bit supplied to a terminal (d) and stops the counter 81 when the said expanded signal level reaches the uniformly quantized input signal or over. The value is equal to the input signal address and represents the compressed signal level.

Title: Device for checking surface of cylindrical body
Inventor: MIYAGAWA MICHIAKI
IPC: G01B11/30
Filed: 1981-01-27
Abstract: PURPOSE:To implement the high speed checking processing by comparing the minimum value of the interval between the pulses of a binary coded signal of a sensor output based on the reflected light from the surface to be checked with a specified threshold value. CONSTITUTION:The reflected light from the rotating surface to be checked having seamed parts is detected by a fiber sensor 601. The output thereof is guided to polarity discriminating circuits 606-608 through BPFs 603-605 having different cut off frequencies, and only one polarity is extracted. The signals are compared with a specified DC level in comparators 609-611, coded to the binary signals, and inputted to preprocessing circuits 612-614. Parts of the signals are directly inputted to a pulse interval measuring circuit 616, the other parts are inputted to the circuit 616 through an OR circuit 615, and the pulse interval is obtained. The signal from the circuit 616 is inputted to a minimum value detecting circuit 617, and the minimum value of the pulse interval is compared  with the threshold value in a judging circuit 618. If the signal is small, it is determined that the product is defective. Thus the high speed checking process  can be implemented by the inexpensive means.
